Resumo: Bentonites are extensively investigated for acting as viscosifying and stabilizing agents for emulsified fluids. The properties of drilling fluids are extremely important for the success of oil well drilling. However, the purification of clays is necessary to promote an improvement in the rheological behavior of the dispersions. Like natural bentonite clays, organophilic clays obtained from sodium bentonite clays are of enormous industrial importance due to their high degree of swelling in water, and quarternary ammonium salts. In this study, the influence of the clay type is investigated rheologically in emulsified fluids of different mass proportions oil/water (O/W): 50/50, 70/30, 80/20, 90/10 and 95/05 under the concentration 6000ppm. The clay samples were characterized by FRX, DRX AND TG/DTA. All oil-based emulsified fluids were analyzed through macroscopic and rheological morphological observations. Purified sludge green (hydrophilic) and organophilic sludge green (hydrophobic) clays were tested as viscosifying and stabilizing agents for emulsions. From the results, it was possible to verify the chemical composition of the clays, with the organophilic clay being the one with the greatest loss to fire, the efficiency of the surfactant intercalation in the slime-green organophilic clay shown in the X-ray diffractograms, as well as the events of mass loss, where the organophilic slime-green showed a greater loss. Rheologically, the results confirmed that only the emulsion containing sludge-green clay of mass fraction 50/50 (O/W) was physically stable.

Las propiedades de los fluidos de perforación son extremadamente importantes para el éxito de la perforación de pozos de petróleo. Sin embargo, la purificación de arcillas es necesaria para promover una mejora en el comportamiento reológico de las dispersiones. Al igual que las arcillas de bentonita natural, las arcillas organofílicas obtenidas a partir de arcillas de bentonita de sodio son de enorme importancia industrial debido a su alto grado de hinchamiento en agua y sales de amonio cuaternario. En este estudio, la influencia del tipo de arcilla se investiga reológicamente en fluidos emulsionados de diferentes proporciones de masa aceite / agua (O / W): 50/50, 70/30, 80/20, 90/10 y 95/05 bajo el concentración 6000ppm. Las muestras de arcilla se caracterizaron por FRX, DRX Y TG / DTA. Todos los fluidos emulsionados a base de aceite se analizaron mediante observaciones morfológicas macroscópicas y reológicas. Se ensayaron arcillas verde de lodo purificado (hidrófilo) y verde de lodo organófilo (hidrófobo) como agentes viscosificantes y estabilizantes para emulsiones. A partir de los resultados, se pudo verificar la composición química de las arcillas, siendo la arcilla organofílica la que presenta mayor pérdida al fuego, la eficiencia de la intercalación del surfactante en la arcilla organofílica verde-limo mostrada en los difractogramas de rayos X , así como los eventos de pérdida de masa, donde el verde-limo organofílico mostró una mayor pérdida. Reológicamente, los resultados confirmaron que sólo la emulsión que contenía arcilla verde fangosa de fracción de masa 50/50 (O / W) era físicamente estable.As bentonitas são amplamente investigadas por atuarem como agentes viscosificantes e estabilizantes de fluidos emulsionados. As propriedades dos fluidos de perfuração são extremamente importantes, para o alcance do sucesso da perfuração do poço de petróleo. Todavia, a purificação das argilas se faz necessário para promover uma melhora no comportamento reológico das dispersões. Assim como as argilas bentoníticas naturais, as argilas organofílicas obtidas a partir de argilas bentoníticas sódicas possuem uma gigantesca importância industrial devido ao seu alto grau de inchamento em água, e sais quarternários de amônio. Neste estudo, a influência do tipo de argila é investigada reologicamente em fluidos emulsionados de diferentes proporções mássicas óleo/água (O/W): 50/50, 70/30, 80/20, 90/10 e 95/05 sob a concentração de 6000ppm. As amostras de argilas foram caracterizadas por FRX, DRX E TG/DTA. Todos os fluidos emulsionados de base oleoso foram analisados através de observações morfológicas do tipo macroscópico e reológico. As argilas bentoníticas verde-lodo purificada (hidrofílica) e verde-lodo organofílica (hidrofóbica) foram testadas como agentes viscosificantes e estabilizantes das emulsões. A partir dos resultados, foi possível verificar a composição química das argilas, sendo a argila organofílica a de maior perda ao fogo, a eficiência da intercalação do surfactante na argila verde-lodo organofílica denotada nos difratogramas de raios X, assim como, os eventos de perda de massa, onde a verde-lodo organofílica apresentou uma maior perda. Reologicamente os resultados confirmaram que somente a emulsão contendo argila verde-lodo organofílica de fração mássica 50/50 (O/W) apresentou-se estável fisicamente.Research, Society and Development2021-03-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1292710.33448/rsd-v10i3.12927Research, Society and Development; Vol. 10 No. 3; e3910312927Research, Society and Development; Vol. 10 Núm. 3; e3910312927Research, Society and Development; v. 10 n. 3; e39103129272525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/12927/11705Copyright (c) 2021 Wênnya Joyce Carneiro Rodrigues Ramalho; Matheus Ferreira de Souza; Heber Sivini Ferreirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRamalho, Wênnya Joyce Carneiro Rodrigues Souza, Matheus Ferreira de Ferreira, Heber Sivini 2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/12927Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:22.715453Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
